Summary
Despite advances in prevention and antiretroviral therapy (ART), AIDS persists. New antiretrovirals (ARVs) and therapeutic strategies are crucial for managing HIV/AIDS effectively.
Area of Science:
- Virology
- Immunology
- Public Health
Context:
- Acquired immunodeficiency syndrome (AIDS) remains a significant global health challenge.
- Current antiretroviral therapy (ART) has limitations and necessitates ongoing research.
- Prevention efforts alone have not eradicated the disease.
Purpose:
- To highlight the ongoing need for novel antiretroviral (ARV) drugs.
- To discuss the development of new therapeutic strategies for HIV/AIDS management.
- To emphasize the evaluation of critical factors in new ARV development, including toxicity, resistance, drug interactions, cost, and adherence.
Summary:
- New ARVs are progressing through clinical trials.
- Therapeutic strategies focus on mitigating risks and improving patient outcomes.
- Fixed-dose combination coformulations offer significant advantages for ART adherence and quality of life.
Impact:
- Advances in ARV development are crucial for overcoming treatment challenges.
- Improved therapeutic strategies can lead to better patient adherence and reduced healthcare costs.
- Continued innovation in HIV/AIDS treatment is essential for public health.

Retrovirus Life Cycles
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...
Retroviruses
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
Subviral Agents
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...
Immunodeficiency Diseases
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

Inhibitors of Viral Protein Synthesis
Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
Mechanisms of Retrovirus-induced Cancers
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...
